My friend, reporting the furthest position examined by the parser I have
useful in error cases as a simple stop gap when using a combinator approach.

Thinking about it you kind of want to see the furthest failed position and the
stack of rules above it. Such requires meta information when the code is
written in the most natural way. For this reason and others I believe it is
good to represent your grammar in data structures which is further in the
direction of a compiler compiler tool (or compiler interpreter tool).
